LBL D

Maybe I don't get the point and this is a very silly question, but...
...why don't you just replace LBL 1 with LBL C and LBL 2 with LBL D ?

Great. That's an even better version that can be extended to five currencies.

Idea: what about another CHS after the multiplication? This way the output is flagged just as the input. So you know that positive input/output means USD and negative values are EUR or GBP.

I believed is the Updated II
Personally I like Updated III

Then leave it the way it is. I'm glad you like it. ;-)

Finally, here is an "extended version" for five currencies that does the same thing via indirect addressing.
Store the conversion factors in R1, R2, R3, R4 and R5 respectively.

Code:

LBL A
1
GTO 0
LBL B
2
GTO 0
LBL C
3
GTO 0
LBL D
4
GTO 0
LBL E
5
LBL 0
STO I
R↓
x>0?
GTO 1
RCL (i)

CHS
RTN
LBL 1
RCL (i)
